ICD-10 Code B58.00 – Toxoplasma oculopathy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B58.00 – Toxoplasma oculopathy, unspecified
What it is
This code identifies eye disease caused by Toxoplasma infection when the documentation does not specify the exact ocular site or type. Use it for toxoplasmosis affecting the eye without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include ocular inflammation, reduced vision, floaters, or retinal lesions consistent with toxoplasma eye involvement.
When to use this code
Use B58.00 when the provider documents toxoplasma oculopathy or ocular toxoplasmosis but does not name a specific subtype. It also fits when the record confirms eye involvement from Toxoplasma and the laterality or exact manifestation is not stated. Check documentation if the note is unclear.
Do not use for
Do not use this code for toxoplasmosis without eye involvement, or when a more specific ocular toxoplasmosis code is documented. Avoid it if the chart describes another eye disorder unrelated to Toxoplasma.
Coding tip
If the note says only “ocular toxoplasmosis,” code the unspecified option unless the provider gives a more precise diagnosis.
